- Abstract
The present study comprised 101 (48 men) employees of the Finnish Broadcasting Company with or without irregular shift work, but all with a work week of five shifts in a row followed by 2 days off. The mean age of the subjects was 41·0 years (SD = 9·9). The BiteStrip, a single-use disposable EMG device was used for one night during the work week to detect sleep bruxism. The Actiwatch Plus actigraph was worn on the non-dominant wrist for the entire week to evaluate sleep. Total sleep time and fragmentation index, the latter as a measure of sleep efficiency was calculated for the present study. The BiteStrip scores among the participants were: 0– no bruxism: 52·2% (according to the manufacturer, comparable to a sleep laboratory bruxism count of up to 39 over 5 h), 1– mild: 29·3% (40–74 counts), 2– moderate: 12·0%: (75–124 counts) and 3– severe: 6·5% (>125 counts). Severe bruxers slept less during the work week than non-bruxers ( P = 0·009), but severe bruxers slept slightly more than non-bruxers during days off. The group means of the sleep fragmentation index decreased from start towards the middle of the work week and increased during days off ( P = 0·016). The levels of the fragmentation indices were consistently higher in accordance with bruxism severity ( P = 0·013). It was concluded that bruxism has a coherent relationship with sleep efficiency and it can be detected at home with a low cost device.
